1- As a favor to geofflambert, at the earliest opportunity evacuate the dragons from the island of Komodo before they are captured by the enemy. They will evolve into fierce warriors that know how to make plasma torpedoes.
2- Looking at your now 'rear' areas, build forts every place you can. Sydney, Melbourne, Bombay, and on and on. If he goes deep you won't have enough warning when that happens to get it done. And yes, Pearl Harbor too. You have to decide where the boys build airfields or ports instead to support operations, but neglect the forts at your peril.
3- Only build one thing at a time to build it faster. Switch back and forth after achieving levels of building if you wish, but forts 1 + 99% and airfield 1 + 99% and port 1 + 99% is the same as forts 1/airfield 1/port 1.
4- This is the link for the WITP-AE wiki (
http://witp-ae.wikia.com/wiki/War_in_the_Pacific:_Admiral%27s_Edition_Wiki). People put various articles in there that you might find helpful. I put up one on surface combat intercepts.
5- Search is darn near everything in the naval side of this game. Search will help your subs kill ships. Search will help your surface intercepts, air attacks, and early warning. And search is
very porous in AE - things
will slip through undetected. If you want solid search it has to be overlapping from multiple bases. And do use search arcs, you have better chances of seeing things when focusing the search to the needed vectors.
6- FOW is far superior in AE (to WITP), and is even better in the latest Beta (as opposed to the latest official). Rarely you will even have an enemy LCU in the same hex that you don't see yet.
7- I think others mentioned this, but you must focus big time on getting enough fuel and supply forward.
Lots of other stuff, but this should help.
